Overview

The MCP1642B/D High-Current Synchronous Boost Converter Evaluation Board is used to evaluate and demonstrate Microchip’s MCP1642B/D products. The board can be used to evaluate both package options (MSOP-8 and 2 x 3 mm DFN-8). The MCP1642B/D is capable of regulating the output voltage over 1.8V to 5.5V range and typically can deliver over 400 mA of load current at 3.3V output when supplied from a single 1.5V cell. The Evaluation Board was developed to help engineers reduce the product design cycle time.
